Specification of Letters Patent.

Patented Dec. 25, 1906.

Application filed April '7, 1906. Serial No. 310,488.

T0 a/ZZ whom it may concern,.-

' at Westpoint, in the county of Lawrence,

State of Tennessee, have invented certain new and useful Improvements in Stovepipe- Braces; and I do hereby declare the following to be a full, clear, andexact description of the invention, suchl as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to means for bracing and supporting a stovepipe so that the joints or lengths will not become disjointed and so that the pipe may be sustained in proper position oralinement, particularly when the pipe is unusually long.

It is the object of the invention to rovide a brace-rod securely sustained in p ace, to which brace-rod devices in the form of a .pinch-collar are attached, which devices in turn embrace and hold the stove ipe in place and secure its terminal to an in the flue and secure it against entering too far.

- The nature of the invention is indicated in the foregoing statements and is to-be ascertained in detail from the following speciication in view of the appended drawings, forming a part thereof, to which reference is to be had. j

Of the said drawings, Figure 1 is a side elevation of a stovepipe with the invention a plied. Fig. 2 is a section on line 2 2 of ig. 1. Fig. 3 is plan showing the manner of connecting the ipe with theflue.

Like figures ofD reference designate like partswherever they occur.

In a detailed disclosure of'my invention, let 10 designate the stovepipe which is attached, as usual, at one end to a stove 11 and runs from thence up to the chimney or flue 12, which it enters.

13 designates a brace-rodwhich, like the pipe, extends from the stove to the flue and in proximity to the pipe. The brace-rod is connected tothe wall where convenient by suitable means V(r"1ot"sh'own) `and is also sustained by rods 4or small chains'ltfconnected at the upper end to the ceiling and'at the lower end to the brace-rod at each elbow.

may be secured tothe stove, and the rim or extension 40 may be internally screw-threaded to receive the lower end of the brace-rod,

to be working apart bac which may be provided with an external screw-thread of a nature to coact with the screw-thread of the rim 40, and the said brace-rod may be made in sections, each two sections being connected by a turnbuckle 16, which latter means may be three inches in length.

The stovepipe will be constructed of joints or lengths corresponding to the length of the sections of the brace-rod secured together by having one end telescope the end of the adjacent section, as is usual, and to keep the joints from becoming disjointed or separated the turnbuckles may be adjusted from time .to time, if necessary, so as to have the clamps on opposite sides of a joint or connection operate on the pipe with a tendency to draw joints or sections of the pipe that may seem toward each other or in a direction having a tendency to close the joint.

As shown in Fig.l 1, for a mere example, it may be assumed that the connection or joint x" has been seen to have a tendency to separate, and upon this discovery the turnbuckle 16 will be operated so as to cause the clam s 17 to draw the sections or joints of' pipe etween the latter in the direction of the arrows marked on the pipe. This will oper- .ate to keep the said connections or joints from separating.

In Fig. 1 turnbuckles 16 are shown as aty tached to the ends of brace-rods 13, and from this view it will be seen that the said turnbuckles are of ordinary construction, being turned on the opposite ends of the rods 13,

the said ends of the rods being provided withk screw-threads that on one end are urighthanded and on the other are left-handed,

the internal thread on the ends of the turn-V buckles being of a similar character, so that when the turnbuckles are revolved in one direction they will draw the ends of the bracerods together and when revolved in the opposite direction they will move said ends of the rods apart. The exterior of the turnbuckles are in form that of an Octagon in cross-section, so that a secure grip vmay be readily hadl thereon:

Referring to Fig. 2, which shows a clamp\ for the brace-rod and stovepipe, it will be seen that each clamp 17 for a brace-rod 13 is formed as a pinchcollar, the ends of the collar terminating in parallel parts 18, which IOO are drawn together to pinch the collar 17 around the brace-rod by a bolt and nuts 19 and 20, respectively. From the outer ends of the parallel parts 1S there extend iingers 21, which embrace the stovepipe and are tightened thereabout by the same means that tighten the pinch-collar on the brace-rod, all as will be clearly understood by reference to said Fig. 2.

In Fig. 3 there is represented a form of means for clamping the end of the stovepipe to the lue.- In this ease the end ofthe stovepipe enters the thimble 23 in the opening provided therefor in the flue andis secured therein by set-screws 24. A rectangular frame or block 25 above the thimble has two clamprods 26 26 passed therethrough in opposite directions, each rod being provided on its outer end with a clamp-hook, one of which hooks engages one side of the breast of the iiue or chimney and the other hook the other side of the breast. The hooks will be pressed forcibly toward each other and take in the side walls of the flue to a considerable degree, and a set-screw 27, turned into the block 25, will engage and hold the clamp 26 in adjusted position, and the other set-screw 27 will be turned down and act in like manner on the clamping-rod 26 and hold it in adjusted position, and in this manner the stovepipe will be held in the thimble of the ue and at the same time prevented from entering it too far.

At each elbow it is proposed to construct the brace-rod with a short section covering the turn or elbow and provide the said bracerod with a turnbuckle at each side of the turn, bringing the said two turnbuclrles quite close together with a single clamp of the stovepipe to the brace-rod at the corner between the two turnbuckles. Under this construction the stovepipe has substantially twice the support from the brace-rod at the pipes elbow from what it has elsewhere, and beside the support of the brace-rod from the ceiling at the elbow-point provides for increased steadiness of the parts at this point.

As before stated, there will be one clamp for each section or joint of stovepipe, which will be located on the brace-rod, so as to cngage the pipe at a oint substantially between its ends, and a turnbuclile will be provid ed at each junction of two lengths of brace-rod which will be arranged to occur at a point substantially intermediate of two clamps.

Of' course the invention may be employed on furnace-pipes or other smoke conveyers or pipes than those leading from stoves.

1. The combination with a stovepipe, of a brace-rod extending in close proximity to the pipe, clamps engaging the rod and pipe for sustaining the latter in proper position, a lluo, and means exteriorly secured to the llue and connected to the brace-rod for maintaining the pipe in properly-adjusted position in the lue.

2. The combination with the stovepipe, of the brace-rod extending in close proximity thereto, of a clamp having the form of a pinch-collar for adapting it to be clamped on the pipe, curved ingers extending from the ends of the pinch-collar adapted to embrace the stovepipe, and means for clamping the pinch-collar on the rod and the curved iingers on the stovepipe.

3. The combination with. a stovepipe, of a brace-rod to support the same extending in close proximity thereto, an elbow .in the stovepipe, a corresponding bend in the bracerod, and supporting means connected at the upper end to the ceiling and at the lower end to the rod at the point of the bend therein.

4. The combination with a brace-rod for supporting a stovepipe, of a support or step for the lower end of the rod, said support consisting of an annular plate with an interiorly-screw-threaded extension, the said rod being exteriorly screw-threaded at its end and adapted to be screwed into said extension.

In testimony whereof I allix my signature in presence of two witnesses.

WILLIAM I-I. J. CLIFTON.
